Perceive health

Empaths have a special ability to perceive the life essences of the people and animals (and some highly-evolved intelligent plantlife) around them. This action trains empathy and power perception. As they gain skill, these sensations gain clarity and they'll be able to pick out certain properties of the individual (whether in hiding, if they have a disease, etc).

Notes

1. The types of things you can sense (see above list and table) appear every 50 combined ranks between Empathy and Power Perception. It is possible you may get lucky and see them very rarely before this point, but it appears to always be close to the 50-rank mark (within 20 ranks).
2. The range you can sense seems to grow every 200 combined ranks in Empathy and Power Perception. It is similarly possible this will happen earlier than expected.
3. The total number of individual essences you can sense is also limited by your skill. If you exceed this amount, your senses will become overwhelmed and you will be stunned for a moderately long time. Though it will not always happen, you can receive internal injury to your head and nerves.
